NASA Detects Sunspots as Sprays of Plasma Formed on the Surface; Will It Turn Into a Solar Storm?
Close NASA satellites discovered a sunspot on our Sun's surface as our host star sprayed plasma on the surface. This could result in a solar flare with a speed of 1.8 million kilometers per hour. Since sunspots have high magnetic fields, these plasmas are usually hotter.
